I then argued that Raman did not object to Compton’s discovery of the Compton effect because Compton interpreted it on the basis of light quanta, but for more technical reasons. Raman’s remarks to Compton at the BAAS meeting in Toronto in 1924 thus should not be interpreted as resistance to Einstein’s light-quantum concept, even though Raman later derived the Compton wavelength shift on the basis of the electromagnetic wave theory.
